IMPROVEMENT IN LAP-BOARDS.

Specification forming part of Letters Patent No. 130,094, dated July 30, 1872.

To all whom it may concern:

Be it known that we, WILLIAM B. WHITE, of Abington, and BRADLEY S. BRYANT, of Hanson, both in the county of Plymouth and State of Massachusetts, have invented a new and useful Improved Lap-Board and that the lap-board made of binders, paste, or straw board, with metal around its edges, as hereinafter set forth.

In the accompanying drawing our improved lap-board is illustrated, the figure being a plan view of the same.

A in thedrawing represents our improved lap-board, made of binders board cut out the usual size and shape for wood lap-boards. b is a metallic band or strip applied to the edges of the board A around its entire periphery, covering said edges and overlapping them and securing them together. B is a graduated scale of inches, subdivided into sixteenths or other smaller or larger equal divisions, which graduated scale is along the metallic binding b for a portion of its length.

A board made as described is simple, cheap, strong, tough, and light, and not liable to crack or warp.

The board is surfaced with sheets of cloth or paper or flocks of cotton, wool, or other material, applied either direct or through a paper or cloth sheet, usinga proper cement.

The graduated scale B enables lengths to be measured at pleasure, and being along the edge and formed upon the metallic binding is in the most practical and convenient form.

Having thus described .our invention, what we claim as new, and desire to secure by Letters Patent, is-

The lap-board made of straw-board, surfaced as desoribed, and bound with the plate b, having the scale B, all constructed as set forth.

The above specification of our improved lapboard signed us this 29th day of November, 1871;
